【 摘 要 】

Zaohe Lock was built in the 1950s and has a long running time. The bottom plate, gate pier and apron (covered) parts of the gate were sampled this time, and concrete samples were tested for related performances at the same time, including microscopic pore structure, micromorphology and chemical composition. The results of this experiment will help us to understand the changes in physical and mechanical properties of underwater concrete and its durability changes, revealing the macro and microscopic performance evolution mechanisms of concrete materials, and providing technical reference for the durability design of related hydraulic structures.
